Distribution of estimated glomerular filtration rate (eGFR) and time between vascular access (VA) creation and first hemodialysis in VA created timely and not timely by eGFR slope group. eGFR slope by 75th, 50th and 25th percentiles (a,c) and eGFR slope by clinical recommendation (b,d). Asterisk in (a) represents the significant difference between slope groups in the group comprising VA created timely (P = 0.02), and there was a non-significant difference between slope groups in the group comprising VA created not timely by the Kruskal–Wallis test. Asterisk in (c) and (d) display the significant difference between slope groups in the group comprising VA created timely (P < 0.001), while there was a non-significant difference between slope groups in the group comprising VA created not timely by the Kruskal–Wallis test.
